Abstract: This disclosure provides systems, methods, and devices for memory systems that support encrypted data in transit for Replay Protected Memory Blocks (RPMBs). In a first aspect, a method of processing data for a memory system includes receiving an authentication key from a host device for authenticating access to data stored in a portion of the memory module; deriving an encryption key based on the authentication key; and processing data transmitted on a first interface between the host device and the memory system based on the encryption key. Other aspects and features are also claimed and described.

Abstract: A motor control circuit includes a switch circuit powered by a power supply to drive a motor to output a motion. A switch drive circuit sends a valid drive signal to the switch circuit to drive the motor to output the motion. A limit switch is associated with a position of the motor's motion output, enabling the motor to generate a feedback signal when the motor outputs the motion to the position in a direction. The switch drive circuit receives the feedback signal to cut off power from the power supply to the switch circuit, and the motor stops outputting motion. The motor control circuit feeds from the limit switch back to a controller. When the direction of the motion output by the motor is switched, the power from the power supply to the switch circuit is turned off using the feedback signal.

Abstract: Disclosed in the present embodiments are a foldable pressing device and an X-ray machine. The foldable pressing device includes a motor, a lifting member, a pressing member, a linear guide member with a stop position, a pulling member and a resilient member. The lifting member, driven by the motor, causes a sliding element in the linear guide member with a stop position and the pressing member to move upwards. When the sliding element arrives at an uprising stop position, the pressing member, under the effect of the lifting member and the pulling member, overcomes the resistance of the resilient member to realize the folding thereof. The lifting member, driven by the motor, drives the pressing member to move downwards, and the pressing member is unfolded under the effect of the resilient member.
